The same thing happened here in WA back in the summer and some of the motorists caught it on video cameras. There was a huge public outcry and the police started cracking down on bikers after it. Lot’s of innocent folk getting harassed and getting tickets for anything and everything. One dude got pulled over after standing on his pegs to stretch his legs. Some motorist freaked out and called 911 on him and reported he was doing wheelies. Now that I think about it, I think he was charged on suspicion of dangerous driving. I think if someone calls 911 and makes a complaint against you the police can arrest you on suspicion of that charge. The officer did not see you commit the offense but have someone willing to testify against you.
If this is happening in your area, make sure you are 100% legal or expect to get a ticket.
